The advantage of this construction is, that for a comparatively small additional cost a mill can be furnished on which logs of various sizes can be sawed at the best advantage.

What we claim as new is 1. In a saw-mill, the combination, substantially as set forth, of a reciprocating 10g carriage, a supporting frame-work at one side of said carriage, a circular-sawdriving mechanism, and a band saw driving mechanism mounted on said frame-work in a manner, substantially as set forth, whereby the saws driven by said mechanisms will operate in a common vertical plane lying between Said carriage and the said frame-work.
